So. DH had an appointment yesterday in the afternoon. He decided to take a nap around noon, I offered to wake him up.
DCs get restless; I decide to take them outside. Phoned DH at required time, but no answer - because he'd switched his phone off, to which he's normally wedded.
I have to admit - I was vaguely aware that this could be a possibility, so effectively took a risk when I decided to phone rather than go back home. However, He did nit tell me tgat he'd switch off his phone explicitly.
He woke up too late. My fault?
